Episode summary

Ryan Nelsen came to Cannes for the same reason most leaders do: the people. He spent the week in client meetings and CMO roundtables, and his read on the dominant theme is specific. Last year the industry talked about what AI would become. This year it is about outcomes and execution, moving from experiments to what he calls AI orchestration, coordinated end to end from the start of a campaign to the result.

What struck him in those rooms is that a week of AI talk kept circling back to people. His line is worth keeping: use AI to automate systems and process, but do not use AI to automate your point of view as a marketer. The creativity is the part to protect.

StackAdapt is the platform underneath that view. It is an AI advertising platform, a DSP, where brands and agencies buy across connected TV, digital out of home, audio, video, and podcasts, load their creative, find their audiences, and get measurement that improves with AI. With more than 40,000 brands on the platform, StackAdapt sees what works, which is what powers Ivy, its AI assistant. Nelsen describes Ivy as proactive AI: you open the platform in the morning and it hands you the specific optimizations to make, rather than making you dig through dashboards to find them.

His advice for getting started is refreshingly plain. It does not need to be hard, so start small, and test and iterate. Let the platform carry the math, and put your energy into the ideas. And on trust, he offers the most human frame of the conversation. The people you trust most give more than they take. Brands earn trust the same way, by making deposits rather than withdrawals.

Key takeaways

  • 00:21 Cannes is about relationships; StackAdapt came for back-to-back client and partner meetings.
  • 01:21 The dominant theme moved from AI experiments to execution, what Nelsen calls AI orchestration, coordinated end to end.
  • 02:00 Use AI to automate systems and process, but never to automate your point of view as a marketer.
  • 02:42 StackAdapt is an AI advertising platform (a DSP) for buying across CTV, digital out of home, audio, video, and podcasts, with AI-driven targeting and measurement.
  • 03:49 With 40,000 brands on the platform, StackAdapt’s Ivy assistant uses proactive AI to surface the day’s optimizations instead of making you dig through dashboards.
  • 04:40 Getting started: keep it simple, start small, and test and iterate; let the platform handle the math so brands focus on creativity.
  • 05:27 Brand trust works like any important relationship: make deposits, not withdrawals.

Questions people ask

Who is Ryan Nelsen?

Ryan Nelsen is the Chief Marketing Officer of StackAdapt, an AI advertising platform. He was appointed CMO in 2024 and speaks about AI orchestration, keeping marketing human, and brand trust.

What is StackAdapt?

StackAdapt is an AI advertising platform, a demand-side platform (DSP). Advertisers, brands, and agencies use it to buy ads across connected TV, digital out of home, audio, video, and podcasts, upload creative, target audiences, and get measurement and reporting that improves with AI. More than 40,000 brands are on the platform.

What is AI orchestration?

AI orchestration is Nelsen’s term for where the industry has moved: from talking about the future of AI, to experiments, to execution. It is about coordinating AI end to end, from the very beginning of a campaign through to the outcomes marketers are trying to drive.

What is Ivy from StackAdapt?

Ivy is StackAdapt’s AI assistant, launched in 2025. Nelsen describes it as proactive AI: instead of poking around dashboards, you open the platform in the morning and it tells you the specific optimizations it recommends, for example seven things to act on today.

Should marketers use segmentation or signals?

Both. Nelsen says both segmentation and signals are important when finding and targeting audiences, and the advantage right now comes from learning, testing, and iterating faster than competitors.

How should brands build trust?

Nelsen frames brand trust like the most important relationships in your life: the people you trust give more than they take. Brands should do the same, making deposits into the relationship rather than withdrawals, and using AI to automate systems and process without automating the marketer’s point of view.

Full transcript

Jeanniey Walden: Hey Ryan, thanks so much for joining me here to talk about what’s happening at Cannes, why you’re here, what you’re looking forward to, and what you think is going to happen in the future.

Ryan Nelsen: Very excited to be here. Thank you.

Jeanniey Walden: As I’ve been interviewing people, I’ve been asking them the same thing. What did you expect to hear being spoken about at Cannes? Some people have been surprised, and others said it’s exactly what they thought. Why did you come to Cannes? What were you looking forward to the most?

Ryan Nelsen: I think this industry is about relationships, and a lot of the CMOs and top leaders are here, so I love learning from each of them. I’ve had a chance to join several CMO roundtables this week, great discussion, but it comes down to the people. And mostly for us at StackAdapt, we’re here to meet clients and partners and make sure they’re being taken care of.

Jeanniey Walden: I heard that Cannes is the place where business actually gets done, versus some events where it’s really just networking. Are you getting business done here?

Ryan Nelsen: Yeah, back-to-back meetings with clients. There’s a lot of places we could and should be, and there’s so much going on here, but we’re prioritizing client meetings first, and in between, fitting in some other things.

Jeanniey Walden: I’ve been hearing different tracks of conversation. Some have said AI, some retail media and commerce media, some the business of news. What have you been hearing most?

Ryan Nelsen: I think it comes down to AI orchestration. It’s a hot topic for us. Last year we were talking about what the future would be with AI. Now it’s about outcomes and how you make that a reality. It’s gone from experiments to execution, and the orchestration of what that looks like end to end, from the very beginning to all the outcomes we’re trying to drive.

Jeanniey Walden: Have the conversations been more strategic or more tactical? Because I’ve been in both, and it’s really interesting.

Ryan Nelsen: I’ve had several roundtable chats, and what’s fascinated me is that even though AI is the topic, it keeps coming back to human. How do we keep this industry human? How do we keep the creativity? We go do more with AI, but I have this thought: we should use AI to automate systems and process, but we should not use AI to automate our point of view as marketers.

Jeanniey Walden: For people watching and listening, because it’s a podcast and a TV show, tell everybody what StackAdapt does, so they understand why that resonates with you.

Ryan Nelsen: We’re an AI advertising platform, a DSP in the easiest sense of the word. Advertisers, brands, and agencies can buy ads across connected TV, digital out of home, audio, video, podcasts, and more. They come to us, upload their creative, find their audiences and personas, and we help them target those audiences across basically every channel. Then we give them measurement and reporting, and with AI it gets better, faster, and more personalized, so they can drive the outcomes they want.

Jeanniey Walden: Are you in the bucket of segmentation or signals when you’re looking for audiences?

Ryan Nelsen: I think both are important.

Jeanniey Walden: When you’re talking about AI automation to build these audiences and advertise across networks, where do you see retailers going? Are they hitting walls and looking for new audiences? Using it for loyalty? How do you see people most effectively using what you do?

Ryan Nelsen: It comes down to understanding your audience, and there are competitive advantages right now with AI. The faster we’re learning, testing, and iterating, the faster we gain that edge. We have a lot of data on the platform, 40,000 brands, so we see a lot of campaigns that are working and things that could be optimized. We recently launched Ivy. You wake up in the morning, open the platform, and it says, I have seven things for you today, do you want me to optimize these? This is what we recommend. So rather than poking around dashboards, it’s proactive. We call it proactive AI.

Jeanniey Walden: I love that. It makes so many people’s lives easier. So if someone’s getting started with advertising on an AI platform, what are the three things they need to know?

Ryan Nelsen: At the end of the day, it doesn’t need to be that hard. Start small in some ways, and test and iterate. This is a creative festival, but the math behind these campaigns, we can take care of a lot of that. We want the creativity, the ideas, and to help brands be successful. We have an easy-to-use platform, and we’re known for that, but we’re known for our people as well.

Jeanniey Walden: Last question. You made the platform easy, you leverage AI to take out the questionable elements people spend hours on. Do you think it still comes down to trust with brands? Are brands still needing to develop trust?

Ryan Nelsen: Absolutely. As a CMO, I’m a marketer marketing to marketers, and we use our own platform to promote our brand, so we push our product team as a B2B customer to keep getting better. On brand trust, I always think about relationships. Think about the most important people in your life. They’re most likely giving you more than they’re taking, depositing into your life versus making withdrawals. Brands need to do the same. To build big brand trust, we’ve got to make deposits, not withdrawals.

Jeanniey Walden: That’s awesome. Thank you so much for coming on and sharing your thoughts. Everybody, stay tuned. We’ll be right back.

Ryan Nelsen: Thank you.
